Black Holes as the Nemesis of Galaxy Formation
Galaxies fall into two clearly distinct types: active, blue-sequence galaxies that are rapidly forming young stars, and passive red-sequence galaxies in which star formation has almost completely ceased. These sequences...
Black Holes: Illuminating the Early Universe with Radiative Transfer Simulations
State-of-the-art observations show that within approximately 1 billion years after the Big Bang, all of the primordial hydrogen that permeated the immense space between galaxies had been destroyed by high...
COSMOS Consortium
COSMOS consortium researchers exploiting DiRAC HPC Facilities have made progress towards ambitious milestones in five key inter-related areas: (i) extreme gravity, (ii) inflation and the early universe, (iii) cosmic microwave...
ExoMol
To find out what remote planets orbiting other stars are made of, astronomers analyse the way in which their atmospheres absorb starlight of different colours and compare it to a...
Gravitational waves: DiRAC simulations play a key role in gravitational-wave discovery
On February 11 2016, the LIGO collaboration announced the first direct detection of gravitational waves and the first observaton of binary black holes. Accurate theoretical models of the signal were...
Hadron Spectroscopy: Baryon Mass Splittings
In Cheung et al [JHEP 1612 (2016) 089, arXiv:1610.01073] we computed spectra of highly excited charmonia and charmed mesons with light (up and down) quark masses, corresponding to mπ ≈ 240 MeV,...
Heavy Elements: Linking the Nuclear Interaction to the Structure of Heavy elements
A recent international collaboration between the UK, France, US and Canada have performed systematic studies of both nuclear radii and binding energies in (even) oxygen isotopes from the valley of...
Horizon
Initial conditions for galaxy formation simulations are specified within the Λ-CDM scenario by a Gaussian random field. This leads to a troubling lack of control: we often cannot ask precisely...
Lattice QCD and the Search for New Physics
If you could see deep into the subatomic world with slow-motion glasses, you would see empty space teeming with particles, appearing and disappearing in a tiny fraction of a second....
Post-periapsis Pancakes: Sustenance for Self-gravity in Tidal Disruption Events
A Tidal Disruption Event (TDE), which occurs when a star is destroyed by the gravitational field of a supermassive black hole, produces a stream of debris, the evolution of which...
Understanding the Properties and Stability of Matter
The fundamental constituents of the strong force are quarks and gluons, which themselves bind together to form the familiar building blocks of nuclear physics, protons and neutrons. The two most...
